Verdict
The clearest difference is review sentiment: Coin Flow at 100% against CardNav's 30%. Coin Flow also leads on update cadence (every 2 days vs every 6 months) and iOS requirement (10.0 vs 14.0). CardNav's advantage is rating (4.4 vs 1.0) and ratings volume (982 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
CardNav holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: CardNav has 982 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 30% of CardNav's written reviews are positive against 100% of Coin Flow's, so the app with the better star average is not the one people write more warmly about.
CardNav ships an update every 6 months, Coin Flow every 2 days. The most recent releases landed on October 17, 2026 and October 3, 2026 respectively.
